This is all just setup. You're importing some useful modules and
setting up some variables.

Not sure what's going on here; is that something you ran? Did you
create the file in a hidden directory?

I'm not sure about comments, but based on the docs you linked to, I
would try to retrieve some documents. The first block in that page
says:
GET /documents.{response_format}
The response_format will be JSON (you mentioned wanting to use JSON),
so that means you're trying to get /documents.json. Try out the
interactive parameter setting, and then use the button at the bottom
to get a URL. As a bare minimum, it'll be something like this:
https://api.data.gov:443/regulations/v3/documents.json?api_key=DEMO_KEY
(No, I've no idea why it says ":443" in there.)
To do that from Python, make a call like this:
r = requests.get("https://api.data.gov:443/regulations/v3/documents.json";,
params={
"api_key": api_key,
"dktid": docket_id,
})
Add whichever parameters you need in there; it's a plain Python
dictionary, so you can create it any way you like.
That should give you back a *response* object. The easiest thing to do
from there is to turn HTTP errors into Python exceptions, and then get
the results as JSON:
r.raise_for_status()
data = r.json()
At this point, 'data' should be a dict or list with the content that
you want. It's up to you to delve into that.
Have fun! Hopefully that can get you started.
